TVS diodes, or transient voltage suppression diodes, are a type of diode specially designed to rapidly respond to sudden increases in voltage, quickly diverting the surge of power away from sensitive components like microchips or TVs. The ATV02W400-HF from Diodes Inc. is a unidirectional semiconductor TVS device that is designed to protect against ESD, EFT, and lightning-induced surges in automotive applications.

The ATV02W400-HF is a bi-directional protected device capable of absorbing transient voltage from both directions and provides transient protection for circuit components in applications such as automotive electronic control systems, ignition systems, and power supply lines. The device is a low capacitance ESD and EFT protection device for data lines up to 15 kV per IEC61000-4-2; It has a surge withstand capability of >400W for 8/20µs per IEC61000-4-5. The device operates similarly to other TVS diodes, with a breakdown voltage of 22V.

The device’s working principle is simple. When transient voltage is applied to the device, the device turns on and creates a low resistance path, quickly removing the excess voltage. The device then quickly drops to a low impedance, allowing the circuit to rapidly recover from the transient. The device is designed to reverse breakdown when the reverse bias voltage exceeds the breakdown voltage, effectively opening the circuit.

The ATV02W400-HF is designed for use in automotive and other applications where sensitive components need to be protected from ESD and EFT interference. It is highly reliable, as it is designed with a low capacitance to ensure a fast response time. The device is also able to safely absorb hundreds of watts of energy, making it an ideal solution for high-power applications. The device is designed to provide the highest level of safety for automotive and related applications, making it an ideal choice for protecting against ESD and EFT interference.

The ATV02W400-HF is designed to provide robust protection against ESD, EFT, and lightning-induced transients, making it the perfect choice for those applications requiring superior protection. The device’s low capacitance and high surge withstand capability make it an excellent choice for protecting sensitive automotive components. The device is designed to be easy to use and reliable, making it an ideal solution for those looking for reliable protection for their automotive, and related, applications.
